Q

Target Intensity if VO2 is known

A 
Target VO2(lower end of range)= [(0.40) X (VO2 max- VO2 rest0] + VO2 rest
Target VO2 (upper end of range)= [(.89) x (VO2 max- VO2 rest)]  VO2 rest

Q

What is HRR

A

Heart Rate Reserve
the difference between maximal HR and resting HR
Karvonen method:
Target HR (lower end of range)= [(.40) x (HRmax-HRrest)] +HRrest
Target HR(upper end of range)= [(.85) x (HRmax- HRrest)] +HRrest

Q

Muscular Strength vs Muscular Endurance

A

Strength is defined as one-time maximal force that may be exerted & is localized to a joint or muscle group
Endurance denotes the ability to apply a force repeatedly over time. joint and muscle specific

Q

Program modifications for clients with CVD

A
  • deconditioned and low functional capacity clients may need to stary at low intensities (20-30% HRR or VO2R)
  • Target exercise intensity should fall 10-15 bpm below HR that has previously elicited symptoms
  • Beta clockers and HR lowering meds can decrease accuracy
  • RPE levels of 11-13 typically correspond to the target heart rate for cardiac clients first initiating an exercise program. RPE can be progressed (14-16)

Q

Diabetes recommendations

A

3-7/ week, no more than two consecutive days between sessions of aerobic activity because of relatively brief exercise induced improvements in insulin action. avoid exercise during time when hypoglycemic medication is working at its peak. should eat 1-2 hours before exercise

Q

PNF

A

PNF stretching involves both the stretching and contraction of the targeted muscle group. While there are several ways to employ PNF, the most common technique is termed contract-relax. Following the preliminary passive stretch, the muscles is isometfically contracted for 6 s, relaxed for2-3s, then passively moved into the final stretch which is held for 10-30 s. this method is most effective with the use of a trainer to assist the client through the stretch.
